Hide lines on flat surfaces – automatically turns off the visis converted to one or several different triangles or squares (polygons). A curved desk for example has to be approximated by dividing it into many polygons. This option turns off the visibility for some of the polygon lines that do not contribute to the wireframe view of the drawing.ibility of lines that lies on a flat surface (superfluous lines). When exporting, each component has to be facetted. This is a process where each surface
Export to single faces – exports each polygon as a single entity.
